This is a normal part of learning!
Tips to Fix
- Work on multiple sounds/skills, focus on just one for a while
- Mix target words in with non-examples
(example: words with and without final consonants or final /k/ words with other final consonants) - Use minimal pairs with multiple sounds (bat. hat, cat)
-Do auditory discrimination for listening - Auditory tasks where you ask them if they heard the target sound or not
- Repeat their errors back to see if it sounds right
